There is no official support for OpenVPN on iOS. So unless you want to Jailbreak all your devices, there's no way this is going to work.

Instead, you could setup an IPsec VPN using tools like strongSwan or by buying a commercial appliance. An entry level Cisco ASA isn't that expensive, even more so when considering the time it takes to set up and secure something like this yourself.

I had seen that, but it seems not available through AppStore here.

If you can not see any OpenVPN client in the AppStore then you might have to Jailbreak the device to install something like this. Even with my Android phone I needed to root it to uses OpenVPN.

If you want an OpenVPN connection, I suggest getting a DD-WRT supported router, installing DD-WRT firmware that supports OpenVPN, configuring the router properly and then connecting to that router with your iPad.

There's lots of information online about DD-WRT and installs, and it can turn into a real headache. To avoid future headaches, confirm that the router you buy supports DD-WRT with OpenVPN well - again, through searching online and finding answers.
